Pure polyurethane waterproof coating 
 DM-300 
 Advantage 
 A two-component coating, excluding tar pitch, does not contain solvents, safe and nontoxic at room temperature reflects the curing can be used for drinking water projects. 
 High tensile strength, elongation, and resistance to grass-roots deformation ability. 
 (3) high bonding strength, strong adhesion, and the overall water effect. 
 4 chemical resistance, corrosion resistance, aging resistance, high temperature performance. 
 5 for water impermeable concrete surface, using the positive side. 
 Typical performance indicators 
 Tensile strength ≥ 2.45Mpa 
 Elongation at break ≥ 450% 
 Tear strength ≥ 14N/mm 
 Flexibility at low temperature ≤ -35, ℃ 
 Impermeability (0.3Mpa, 30min) impervious 
 Recommended for 
 A roof, terrace, basement, bathroom wall ground water. 
 Water conservancy, tunnels, mines, pool, cable purchase waterproof. 
 (3) building expansion joints, construction joints, settlement surface sealing. 
 4 lap of the waterproofing membrane, sealing, seal. 
 Use 
 The grassroots level to prepare: the base surface structural integrity of a solid, clean, free of loose debris, no oil. If leakage can be used the DM-410 impermeability on the 1st patch. 
 Primer: DM-210 wet-based surface sealer, primer should be painted uniform, not leakage Tu. 
 Three standard ingredients: the ratio of the A / B = 1/1.5 (quality ratio), the two groups were measured separately and mixed with an electric mixer Stir. 
 4 Tu: the primer is dry, then the standard ingredients in the coating, the coating should be vertical, coating interval should be above the coated non-stick feet shall prevail. 
 5 Table Tu: When the coating thickness close to the requirements can be painted table. 
 Amount of reference: the coating thickness of 1mm, with about 1.35 ~ 1.4kg/m2. 
 Packaging: This product with iron packing: group A 15kg / barrel; Group B of 30 kg / barrel
